Abstract

In a reflector-diffuser type liquid crystal display cell, the control electrodes, which are transparent, electronic components and tracks connecting the components to the cell terminals are disposed between the cell front plate and the liquid crystal layer. The counter electrode is disposed on the other side of the liquid crystal layer and has a frosted rough light reflecting and diffusing face over its entire surface situated in the display area and thus itself functions as the cell reflector-diffuser.
